BACKGROUND OF THE INVENTION

The invention relates to a cladding system for a wall. Furthermore, theinvention relates to an arrangement of a cladding system according tothe invention on a wall.

Various cladding systems for walls are known from the state of the art.In particular, they are used for the optical design of the wall and/orfor a protection of a building wall against weather conditions or thelike. The known cladding systems are normally composed of fasteningelements in the form of oblong fastening profiles which can be mountedon the wall and which interact with cladding elements. The claddingelements are plate-shaped and have fastening sections, in particular onthe longitudinal or transverse sides, which interact with the fasteningprofiles in order to connect the cladding elements to the fasteningprofiles. In addition to the intended optical properties of the claddingelements, a number of requirements of such a cladding system are knownto guarantee the intended functionality or the protection of the wallover a long period of time. In particular, gaps or joints between theindividual cladding elements are to be as small as possible. This servesnot only visual reasons, but also to minimize the ingress of rain ordirt into the joints or spaces between the cladding elements.Additionally, the fastening profiles are anchored to the wall or on asubstructure via screw connections, for example. Said screw connectionsare to be covered or disposed so as to be visually imperceptible, ifapplicable, by a corresponding geometric design of the claddingelements.

Specification DE 10 2018 106 155 A1 of the applicant already discloses acladding system for a wall which is realized in a particularlyadvantageous manner with respect to the optical and functional design.In this realization, the individual cladding elements are anchored tothe wall in the area of the longitudinal sides and of the transversesides by means of fastening profiles. Furthermore, the known claddingsystem or the cladding elements are realized as sandwich componentswhich have a core area and cover layers which are made of aluminum andcover the core area on both sides. This material has become known by thetrade name ALUCOBOND® of the applicant and has already proven its worthin the worldwide use for such cladding systems. To fasten such acladding element to a fastening profile, the specification mentionedabove also discloses the creation of folding areas via groove-shapedmilled slots on the cladding elements, sections used for the fasteningto the fastening profile being manually bendable via the folding areas.

From WO 2020/084143 A1 of the applicant, a cladding system having thefeatures of the preamble claim 1 is known. Said cladding system ischaracterized in that it allows an easy mounting on a wall. To this end,two reception sections for fastening sections on the cladding elementsare provided on a fastening profile. An essential aspect is that acladding element which can be anchored to the fastening profile has twofastening sections which are folded in a different manner, wherein theone fastening section is bent in the shape of a U, whereas the otherfastening section is bent in the shape of a V or disposed at an inclinedangle. The section which extends parallel to the plane of the claddingelement on the fastening section bent in the shape of a U of thecladding element makes it necessary for the insertion slot realizedbetween the two reception sections on the fastening profile to have acertain minimum width so that the fastening section can be inserted intothe insertion slot. However, for optical reasons in particular, there isoften a desire to design the insertion slot as narrow as possible. Forthis reason, it is also known from the specification mentioned abovethat the area of the insertion slot and of fastening screws foranchoring the fastening profile to the wall are covered inside thefastening profile by means of a strip-shaped cover element. However, themounting of said cover element causes additional work and increases thecosts. Furthermore, the U-shaped folding of the fastening section on thecladding element requires an additional work step compared to a simple,V-shaped folding.

SUMMARY OF THE INVENTION

The cladding system according to the invention for a wall having thefeatures disclosed herein has the advantage that it allows aminimization of the insertion slot realized between reception sectionsfor the cladding elements while simplifying the mounting process of thecladding system. Furthermore, the cladding system according to theinvention allows an optimized or uniform deformation of the claddingelements when wind forces occur, for example, because the claddingelements have the same shape or same cross section in the area of theirfastening. The manufacturing process of the cladding elements is alsosimplified compared to the state of the art, because the number ofmilling processes required to form grooves for folding is reduced andthe same milling cutter can always be used.

The invention is based on the idea that the cladding elements aredirectly folded to the fastening profile at their fastening sections,namely in such a manner that the insertion slot can be minimized.

Thus, starting from the state of the art according to WO 2020/084143 A1mentioned above, an essential aspect of the invention is that thefastening profile is realized in such a manner that the second receptionsection, like the first reception section, is bent at an inclinedangle—and thus not in the shape of a U—wherein the inclined angle ispreferably disposed between 30 degrees and 60 degrees, particularlypreferably approximately 45 degrees, in relation to the fasteningsurface or to the base surface section of the cladding element, whereina plane aligned with a lateral surface of the reception section assignedin the first or second reception section extends outside the crosssection of a cladding element disposed in the other reception section,and wherein the two reception sections on the fastening profile havereception openings for the fastening sections of the cladding elementwhich are disposed on sides which face one another on the fasteningprofile.

What is more, the latter feature also has the effect that mountedcladding elements block one another in a release direction, ifapplicable, and thus avoiding an unintended release of a claddingelement from the fastening profile. This is of particular importance inconnection with external forces which may occur as a result of windforces or the like.

Furthermore, a realization defined of the cladding system disclosedherein allows a mounting of a cladding element when the fasteningprofile is already fastened to or anchored to the wall. In this process,another (second) cladding element can be inserted into the assignedreception opening of the fastening profile via its fastening sectionwhen a (first) cladding element is mounted on the wall via the firstfastening section by means of the fastening profile, namely in a statein which the fastening section is still flat or is not yet formed. TheV-shaped folding or bending of the fastening section on the claddingelement is almost necessarily realized in a subsequent mounting step,namely in the manner which is required to be able to fasten thepre-mounted cladding element to the wall or to form a plane wallsurface.

Advantageous embodiments of the cladding system according to theinvention for a wall are disclosed in the dependent claims.

Particularly preferably, the two inclined angles of the receptionsections on the fastening profile have the same size. In particular,this means that it is not necessary to pay attention to a specificmounting position of the fastening profile on the wall, because saidfastening profile can be mounted on a wall at two positions which areoffset by 180 degrees to one another.

A preferred constructive embodiment of the fastening profile alsoprovides that the reception sections on the fastening profile each havean extension comprising a support surface on the side which faces awayfrom the fastening surface of the fastening profile, the base surfacesection of the cladding element contacting the support surface on theside facing the first fastening section via a back parallel to thefastening surface, the two support surfaces being disposed parallel toand at the same distance from the base surface section of the fasteningprofile. In addition to the reception of the fastening section of thecladding element in the corresponding reception section of the fasteningprofile, such a realization also causes an additional form-fittingcontact of the cladding element at the fastening profile for the exactpositioning of the cladding element. In particular, this forces thecladding elements to form a plane overall surface or wall façade, evenif, for example, the strip-shaped fastening sections on the claddingelements have different widths or narrow dimensions and thus project todifferent extents into the reception sections of the fastening profile.

To minimize the cross section or the required material of the fasteningprofile, the two reception sections are advantageously disposed atopposite edges of the fastening profile in relation to a transversedirection which extends perpendicular to the longitudinal direction ofthe fastening profile.

Preferably, the fastening or mounting of the individual claddingelements takes place by realizing an insertion slot, which serves forinserting the cladding elements into the reception sections, between thereception sections on the side of the fastening profile which faces awayfrom the fastening surface, the insertion slot being continuous in thelongitudinal direction of the fastening profile.

With respect to the mechanical strength and a relatively low weight, thecladding element is particularly advantageously realized as a sandwichcomponent which has a core area and cover layers which are made ofaluminum and cover the core area on both sides, wherein grooves areprovided at edges and are realized in the area of a cover layer and ofthe core area of the cladding element. The grooves at the edges cause anintended weakening of the material of the cladding element in order tobe able to fold the fastening sections, in particular manually and atthe intended position from the plane of the cladding element. However,alternatively the cladding element can be made of a (single-layer)aluminum plate which has a thickness of approximately 1 mm to 3 mm.

In particular in order to improve the corrosion properties, it isintended that the fastening profile is made of aluminum and is realizedas an extruded part. The fact that the fastening profile is made ofaluminum moreover also allows the particularly simple realization of the(fastening) screws or screw openings, which are provided for theanchoring of the fastening profile to the wall, on the fastening profilewith little effort during the mounting on site.

Furthermore, the invention comprises an arrangement of anabove-described cladding system according to the invention on a wall.The arrangement according to the invention is characterized in that, inrelation to a bottom of the wall, the two reception sections extendperpendicular to the bottom of the wall on the fastening profile. Suchan arrangement of the reception sections and therefore of thecorresponding fastening sections of the cladding elements causes that anaccumulation of water or dirt in the gaps between the cladding elementson the fastening profile is minimized, because the corresponding mediaor substances are transported towards the bottom by gravity.Alternatively, the fastening profiles can of course be fastened parallelto the bottom of the wall, forgoing the advantage mentioned above.

Further advantages, features and details of the invention are apparentfrom the following description of preferred exemplary embodiments andfrom the drawing.

DETAILED DESCRIPTION

In the figures, the same elements or elements having the same functionare referenced with the same reference numerals.

The figures show the essential components of a cladding system 100 forcovering a wall 1 (for reasons of simplification, only FIG. 5 shows wall1). Wall 1 is a building wall or a garage wall, for example. Claddingsystem 100 is substantially composed of a plurality of fasteningprofiles 10 which interact with (flat) cladding elements 50, whereincladding elements 50 are connected to fastening profiles 10 andfastening profiles 10 in turn can be anchored into wall 1 by means offastening screws 2. Fastening profiles 10 in turn are in particulardisposed or fastened parallel to one another on wall 1, namelypreferably perpendicular or parallel to a bottom (not shown) of wall 1.

In a top view, cladding element 50 shown in a detail view in FIG. 1preferably has a rectangular shape and is realized as a sandwichcomponent 52. According to the illustration of FIG. 2, the compositionof sandwich component 52 or of cladding element 50 is composed of a corearea 54 and cover layers 56, 58 which are made of aluminum and covercore area 54 on both sides. Such a sandwich material as described abovehas become known by the name ALUCOBOND® of the applicant and isparticularly characterized by a relatively low weight and good strengthproperties.

On its two opposite longitudinal sides or transverse sides, claddingelement 50 has a first fastening section 60 and a second fasteningsection 62 which are each strip-shaped. The two fastening sections 60,62 are connected in a monolithic manner to base surface section 64 ofcladding element 50 via straight edge areas 63, base surface section 64being plane and rectangular in the exemplary embodiment. According tothe view of FIG. 2, grooves 65 are realized at edges 63, the material ofone cover layer 56 and of core area 54 being removed from the area ofgrooves 65.

Additionally, it is mentioned that base surface section 64 of claddingelement 50 is plane in the shown exemplary embodiment. However, it isalso conceivable to design base surface section 64 in athree-dimensional manner by providing beads or edges, for example, to beable to achieve desired effects of cladding element 50 which areintended for reasons of strength or for optical reasons, for example.Additionally, cladding elements 50 do not have to realize a shared planesurface when said cladding elements 50 are fastened to wall 1. Instead,cladding elements 50 which are inclined in relation to wall 1 can beprovided by providing fastening sections 60, 62 in different widths inorder realize a three-dimensional wall design.

Cladding elements 50 are preferably manufactured by the manufacturer ofcladding elements 50 in standardized sizes having a width between 1 mand 2 m, for example, in the direction of fastening sections 60, 62 anda length between 2.5 m and 3.5 m extending perpendicular to the widthand are already provided with grooves 65 or fastening sections 60, 62.Additionally, cladding elements 50 are preferably delivered ortransported by the manufacturer of cladding elements 50 to the mountinglocation on wall 1 in the plane state of fastening sections 60, 62,i.e., in a state in which fastening sections 60, 62 are not folded fromthe plane of base surface section 64. This is done in particular withrespect to the space requirement which needs to as small as possibleduring the transport of such cladding elements 50.

Fastening profile 10, which is clearly visible in FIGS. 3 and 5, is madeof aluminum and is realized as an extruded part. It is strip-shaped andhas an exemplary width B of approximately 30 mm and a height H ofapproximately 65 mm, the longitudinal direction of fastening profile 10extending perpendicular to the drawing layer of FIGS. 3 and 5.Preferably, the length of fastening profile 10 corresponds to the lengthof fastening sections 60, 62. Fastening profile 10 has a (plane) basesurface section 12 which realizes a (plane) fastening surface 14 on theside which faces wall 1. In a transverse direction which isperpendicular to the longitudinal direction of fastening profile 10,fastening profile 10 has reception sections 16, 18, preferably eachdisposed mirror-symmetrical to a symmetry plane 15, at opposite edgesfor receiving a fastening section 60, 62 of two cladding elements 50.

Just like second reception section 18 assigned to second fasteningsection 62, first reception section 16 assigned to first fasteningsection 60 on fastening profile 10 is groove-shaped and extends in thelongitudinal direction of fastening profile 10, i.e., perpendicular tothe drawing layer of FIGS. 3 and 5. As in particular shown in theillustration of FIG. 4, reception sections 16, 18 which interact withfastening sections 60, 62 in a form-fitting manner can be provided witha saw-tooth-like structure 20 on lateral surfaces 29, 30 which facefastening sections 60, 62, structure 20 causing fastening sections 60,62 to claw into reception sections 16, 18, in particular if a force isapplied to fastening sections 60, 62 against an insertion direction intoreception sections 16, 18.

The two reception sections 16, 18 each extend at an inclined angle α, βbetween 30° and 60°, preferably approximately 45°, in relation to theplane of base surface section 12 or of fastening surface 14. Preferably,the two angles α, β have the same size. A lateral wall 22 which limitsrespective reception section 16, 18 has an extension 24 which realizes asupport surface 26 parallel to base surface section 12 for a basesurface section 64 of cladding element 50. The two support surfaces 26each have the same distance from base surface section 12 of fasteningprofile 10. The two reception sections 16, 18 each realize a receptionopening 31, 32 for respective fastening section 60, 62, the tworeception openings 31, 32 being disposed on sides facing one another onfastening profile 10 or towards symmetry plane 15.

Fastening profile 10 has a continuous insertion slot 34 between bothreception sections 16, 18, the insertion slot 34 extending in thelongitudinal direction of fastening profile 10 and serving for insertingrespective fastening section 60, 62 of respective cladding element 50into corresponding reception section 16, 18.

Additionally, the cross section of fastening profile 10 has one channel35 near both of the two reception sections 16, 18, respectively, channel35 having an additional longitudinal slot 37 and extending in thelongitudinal direction. Channel 35 is used for the fixation of claddingelements 50 by means of additional fastening elements (not shown) in anarrangement on wall 1 in which fastening sections 60, 62 extend in avertical direction in relation to wall 1.

As in particular shown in FIG. 3, base surface section 12 has agroove-shaped recess 36 in central alignment with insertion slot 34,recess 36 extending in the longitudinal direction and preferably beingdisposed in an approximately central area of fastening profile 10 inrelation to the transverse direction of fastening profile 10 or beingaligned with symmetry plane 15. Recess 36 is used for the localizationor marking of the position at which fastening profile 10 can beconnected to wall 1 by means of at least one fastening screw 2 (shown inFIG. 5). Such a recess 36 can in particular be used as a drilling aidfor realizing a corresponding through bore on fastening profile 10, sothat fastening screw 2 can be mounted in a subsequent step.

As FIG. 5 shows, the two base surface sections 64 of the two claddingelements 50 disposed on a fastening profile 10 realize a shared plane orare aligned with one another; this means, for example, that base surfacesections 64 are disposed at the same distance from and parallel to basesurface section 12 of fastening profile 10. As explained above, however,this is not necessarily required. The illustration of FIG. 5 furthershows that cladding elements 50, which are connected to fasteningprofile 10 via fastening section 60, 62 flushes with support surfaces 26of extension 24 via back 68 of base surface section 64 which facesfastening profile 10.

An essential aspect of the arrangement or realization of, in particular,the two reception sections 16, 18 on fastening profile 10 is that,according to the illustration of FIG. 5, in a state in which the twocladding elements 50 are received in reception sections 16, 18 viafastening sections 60, 62, a plane 70 aligning with lateral surface 29in reception section 16, 18 extends outside the cross section ofcladding element 50 disposed in the other reception section 18, 16. Whencladding element 50 is already disposed on fastening profile 10 viafastening section 60, 62, such an arrangement allows an insertion offastening section 60, 62 of other cladding element 50 into receptionsection 16, 18 of fastening profile 10 in a state in which fasteningsection 60, 62 of cladding element 50 mounted last is in a plane withbase surface section 64, i.e. is not yet folded from base surfacesection 64.

Cladding system 100 for a wall 1 as described above can be adapted ormodified in many ways without departing from the idea of the invention.
